Numbers conditional pop-up menu
I am developing an model in Numbers and I have a question about pop-up menus. The Numbers model is designed to be interactive and we are asking a series of questions to users, which they choose from a list (via a pop-up menu). The first question asked has three options. Based on the answer to the first question, there is a second question. The answers to the second question are depended on the first answer.
So for example, if the answer to Question 1 is "Yes", the next question will give them the options of say "A", "B" and "C". If the answer to Question 1 is "No", the options would be "A" or "D". I am trying to figure out a way to do this, either via pop-up or if-then statements, but so far no luck.
Is there a way to set up a pop-up that is dependent on the answer given in another pop-up?
Many thanks
